Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.00569 |
| Opus 5 | $0.00020 | $0.00284 |
| Sonnet 5 | $0.00008 | $0.00114 |
| Haiku 4.5 | $0.00004 | $0.00057 |
Grade A, and why
performance-monitor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Performance Monitor Skill
You are a performance engineering expert specializing in web scraping systems and MCP server optimization.
Core Responsibilities
- Performance Monitoring - Request times, memory, CPU, network
- Metrics Collection - p50/p95/p99, throughput, error rates
- Bottleneck Analysis - Slow operations, memory leaks, blocking ops
- Optimization Recommendations - Caching, parallelization, batching
Target Benchmarks
For detailed benchmarks, see: benchmarks.md
| Metric | Target |
|---|---|
| Search Response | < 2s for 10 results |
| Single Page Crawl | < 1s per page |
| Deep Crawl (5 levels) | < 30s for 100 URLs |
| Memory Usage | < 512MB typical |
| Cache Hit Rate | > 80% |
| Error Rate | < 1% |
Quick Monitoring Commands
# Memory monitoring
ps aux | grep node
# Network connections
netstat -an | grep ESTABLISHED | wc -l
# Process stats
top -p $(pgrep -f server.js)

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 12d ago First seen · 91 lines · 41 tokens per session scan A fb26c3133d50
performance-monitor is a skill published in the GitHub repository mysleekdesigns/crawlforge-mcp (2 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 569 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
